“MyGeiger” is a premium quality Geiger Counter Kit with PIC16F876A and Nokia 5110 graphic LCD. It can be used as a personal dosimeter or as a radiation monitor hardware with our freeware Radiation Logger Windows software or other open software. Logs files are saved on your hard drive.
GM tube, enclosure, TTL module and battery are not included. MyGeiger Kit can be ordered as a soldered module, but minor solder work has to be performed by the customer: soldering tact switches, battery holder wires and connecting external components. Please choose assembling option from drop down menu.
This Geiger Counter board can drive any GM Tube that requires anode voltage of 400V. Tube voltage value is monitored and corrected by microcontroller even when battery capacity goes down. Calibration menu allows adjustment of conversion factor, alert threshold and choose battery type. The display of the digital counter is auto-range and includes CPM value, radiation dose, fast scale baragraph, measurement time countdown, GM tube high voltage reading, sound and battery indicator.
Since 1.03 firmware version "MyGeiger" has moving average algorith. When testing radioactive samples you'll need to wait up to 60 seconds to get full results. If radiation goes dramatically up then alert system will inform you immediately with activating logic 1 level on ALR pin and lighting up LCD backlight for visual signalization. Firmware 1.00-1.02 has dynamic auto-adjusted counting period for CPM. When radiation level goes up, the software will reduce period from 30 seconds to 10 or 5 seconds.
The PCB has several communication pins for connecting external UART module, Arduino, Geiger Bot or Relay module.
Universal SMT DIY Geiger Counter Kit with PIC16F648A. Miniature SMD module with modern components and high quality PCB. This Universal Digital Geiger Kit that can drive almost any popular american and russian GM Tubes, such as SBM-20, SI-29BG, LND712, LND7317 and much more. High voltage value loaded from EEPROM and can be between 300V - 800V. Calibration constant value for conversion from CPM to radiation Dose is also stored and modified via EEPROM byte.
Radiation dose can be displayed in Sievert or Roentgen units. Has CPM, CPS and total events count presented on the display. The dosimeter support Radiation Logger PC software through USB TTL dongle. The PCB has TRRS audio connector for headphones. This kit has very tiny current and can be powered with one lightweight 3.7V Li-PO. PCB design include smart USB charging for lithium battery.
Simple educational DIY Electronic Kit which allow to drive GM Tube, get sound and visual indication of ionizing radiation and also includes INT pin on the PCB for connecting to Arduino. Great Geiger Kit for playing with Arduino and your own code. User manual includes two code examples if you are starter developer.
The project require soldering, you will receive high quality PCB with electronic components. SBM-20 GM tube is recommended, but you can supply any tube that works on 350V-480V anode voltage.
Electronic Kit for building XR2206 based function generator. The board produce high quality sine and triangle waves. Square wave output require external TTL buffer. Sine waves purity can be calibrated to 0.5% THD, without calibration the kit has 2.5% THD. DC output level is equal to DC bias VDD/2, good audio capacitor may be used as bypass.
By default as supplied, kit's frequency ranges selected with jumper, but you can use rotary switch. XR2206 kit has 4 steps frequency's range: (1) 20Hz-100Hz; (2) 100Hz-1KHz; (3) 1KHz-10KHz; (4) 10KHz-100KHz. Output frequency value is controlled with coarse and fine rotary potentiometer. Amplitude of sine output signal can be changed from 0.05V to 2.00V AC peak-to-peak, for triangle waves is from 0.05V to 4.00V AC peak-to-peak.
Generator Kit includes good manual with assembling instruction that make this DIY Kit easy for the beginners.
